Will you pay $500 more for gas this year because of the Iran war? Fact-checking Democrat Ed Markey

Democrats running for reelection this year say President Donald Trump's actions are hurting Americans' wallets, with gasoline prices soaring since the U.S. and Israel attacked Iran.

"At a buck a gallon, every American driver is going to pay $500 more in gasoline prices at the pump this year," Sen. Edward Markey, D-Mass., said March 20 on CNN.

Gasoline prices rose from an average national price under $3 a gallon before the Feb. 28 attack on Iran to almost $4 per gallon now, according to the GasBuddy gas price app.
